My personal solutions for Advent of Code, an Advent calendar with programming puzzles.
| Year | Language | Stars |
|---|---|---|
| 2023 | Kotlin | 38 |
| 2022 | Python | 35 |
| 2021 | Java | 50 |
| 2020 | Haskell | 44 |
For this year, I created a Gradle project and I am using Kotlin (1.9.21). Insert your input files into the src/main/resources directory with file names inputDD.txt where DD is the day of the month (e.g. input04.txt for day 4). Then, you can either run all solutions at once or specify a day by passing it as a parameter.
In 2022, I am using Python 3.11. To run my solutions, create an input directory next to the solutions directory and insert your input files with file names inputDD.txt, where DD is the day of the month (e.g. input04.txt for day 4). Then, you can run the day's Python file from the solutions folder. For example, for day 4 you would run python solutions/day04.py.
For my 2021 setup, I created a Java 17 Maven project that is partially based on Dave Burke's Advent of Code Java template.
To be able to run my code, you first need to insert your input files into the src/main/resources directory with file names inputDD.txt where DD is the day of the month (e.g. input04.txt for day 4). Then, you can run the program with two parameters. The first parameter is the day for which you want to see the solution to your input. The second parameter is the part of the puzzle that you want to see solved (each day's puzzle is split into two parts). If you omit the second parameter, both parts' solutions of the selected day are shown. If you omit both parameters, all puzzle solutions are computed and printed.
Many of my solutions use the Data.List.Split package. If you are using cabal, you can install this package by executing cabal install split.
Each day's solution reads the input file from the path given as the program's first parameter and solves the day's puzzle for that input file. For example, to see the solution for part 2 of day 7, save your puzzle input for day 7 to a file (say input_07.txt), compile day_07_p2.hs and then run .\day_07_p2 input_07.txt.
You can also run the solutions in GHCi without compiling by executing ghci day_DD_pX.hs and then using the function run [input], where [input] is the path to the input file.
